High Level Brake Light - LEDs


Go to solution Solved by Daveb99,

Recommended Posts

My new (to me) Evora NA has a couple of LED's out on the high level rear brake light.   I've done a search on here and can't find anything, am I right in assuming it needs a whole new unit as it can't be repaired?

I'm hoping someone is going to tell me it's from a Vauxhall Corsa and costs under a tenner from a Vauxhall dealer.....

I think it may be from an MG ZR, around £10 +pp ebay 

There was a thread on here that had part number details.

 

Check the part number on yours compared to this..

The MG part is rather inexpensive as a whole, but they can be repaired if you carefully remove the lens (it's adhered to the body). The LEDs are 3V, 7.6 x 7.6 mm P4 through-hole.

I scrapped the OE LEDs and put a red COB strip on instead, using the PCB as a heatsink of sorts.

To finish this one off ….. I bought a genuine Rover one from eBay and fitted it the other day.   Cost £13.50 and I simply cut and soldered the wires, and drilled two holes for the fixing bolts as per the original one.

Straightforward job - and a very cheap fix with the proper part.   Thanks for all the help 👍🏻

Hello

Some of my led are also down, I m interested of your mod, could you give me more details on the parts you used and the way to make the mod?

i have installed transforged rear light so a continuous break led light would complement it well

best regards

You have to open up the CHMSL housing, which is not the easiest to do. Start by removing the foam gasket around the lens. The lens is adhered from the front, so use heat to soften it up and a thin blade to cut the bond. With the lens removed, take the reflector out, and then the PCB is held on with 2 or 3 screws. The wiring is attached to the back of the PCB, and is extremely short, so you may have to cut it to remove the board, and run new wires out the back. 

Once the board is out, I just unsoldered all the LEDs and put an applicable length of adhesive-backed 12V COB LED strip and wired it up. Ditched the reflector and 3D printed a shroud to hide the visible PCB areas and then reassembled. 

I may end up redoing mine, as I'm not 100% satisfied with the visible red COB when the brake isn't pressed. I think printing a white insert to cover it would look better, and closer to how the Afterburners look. 

I put some pics up on a thread on LT here: https://www.lotustalk.com/threads/what-did-you-do-to-your-evora-today.166185/post-6072194

I haven't found any COB strips that have a white silica layer and red LEDs, but there are RGB strips that do have a white silica layer and then multiple LEDs in various colors underneath. They're typically pricier, and the illumination isn't as continuous (you tend to see small circles of light) when showing a single color. 

I've attached the 3D model of the shroud.
